This ten-part series on machining skills for prototype development comes straight from MIT & Erik Vaaler. It's one of the most extensive video tutorials available on the web for machining. MIT's artificial intelligence laboratory's primary work is done for their robotics group. And most of their equipment is unavailable to the public because they're machines that MIT have built directly in their machine shop, or items that came into the shop needing repair. But if you can get your hands on some of these tools and follow along, you'll be one step closer to being a professional machinist. And you don't necessarily need the equipment to learn something about building prototypes.
